Physical layer network coding (PNC) is a promising technique used to improve the network throughput in a wireless two-way relay (TWR) channel. In this paper, the PNC technique is embraced for a TWR-free space optical (FSO) communication link for the full utilization of network resources. Such a scheme is particularly useful in situations where multiple… (More)

Physical layer network coding (PNC) technique has been adopted in recent works for increasing the system throughput in a two way relay channel (TWRC) where two users exchange their information via an intermediate node. In this paper, we investigate the effectiveness of increasing numbers of users for PNC technique where multiple pairs of users swap their… (More)

Physical layer network coding (PNC) improves the throughput in wireless networks by enabling two nodes to exchange information using a minimum number of time slots. The PNC technique is proposed for two-way relay channel free space optical (TWR-FSO) communications with the aim of maximizing the utilization of network resources. The multipair TWR-FSO is… (More)
